[PATCH v3 -next 07/11] serial: earlycon: Ignore parse_options() error code

[Peter Hurley <peter@hurleysoftware.com>]

Because setup_earlycon() continues to attempt console registration
if an error occurred parsing the option string, the actual value of
the error code from parse_options() is ignored.
